FIELD OF INVENTION

The present invention relates to illumination technical field, and moreparticularly relates to an inductive illumination apparatus with sensorfunction.

BACKGROUND

It is a global trend for governments of many countries to advocatepolicy of energy saving and carbon reducing. More and more light deviceshave power saving features. A common way is to dispose sensor devices onillumination apparatuses to detect people movement so that theillumination apparatuses may be turned on or turned off depending onwhether users exist or not.

In conventional art, however, circuit boards occupy certain space andrequire certain structures and thus sensor devices usually need to bedisposed in a peripheral side of illumination apparatuses. In suchdesign, detection areas of sensor devices may have certain differencefrom illumination areas of light emitting modules or may be shielded byillumination apparatuses. For example, to ensure illumination areas oflight emitting modules, detection areas of sensor devices may have biasoffset. On the other hand, if to ensure detection areas of sensordevices, illumination areas of light emitting modules may have biasoffset. In short, current illumination apparatuses with sensor devicesneed to be improved.

Besides, some manufacturers directly dispose sensor devices at centerportions of illumination apparatuses, but such configuration may causesensor devices being suffered from affection of light from lightemitting modules and heat influence and consequently causes sensordevices failing to detect correctly. Moreover, current sensor devicesand light emitting modules are welded on the same circuit boards. If oneof the sensor device or the light emitting module is broken, even theother function normally, the illumination apparatus thereof cannot work.Broken parts cannot be replaced even other parts are normal. It is notfavorable to environmental protection.

In light of this, the present invention provides an illuminationapparatus which circuit board utilizes space well, which sensor devicedetects well, and which sensor device or light emitting module may beeasily replaced, solving problems eager to be solved in this field.

DETAILED DESCRIPTION

Please refer to FIGS. 1 and 2. FIG. 1 is a perspective view of a firstembodiment of the inductive illumination apparatus of the presentinvention. FIG. 2 is an exploded view of the first embodiment of theinductive illumination apparatus of the present invention.

The inductive illumination apparatus 1 of the present invention includesa lamp body 11, a light emitting module 13 and a sensor and drivermodule 15. The light emitting module 13 and the sensor and driver module15 are disposed on the lamp body 11. The light emitting module 13 iselectrically connected to the sensor and driver module 15. In apreferred embodiment, the light emitting module 13 and the sensor anddriver module 15 are welded with electrical lines or electricallyconnected with electrical connection terminals (not shown). In addition,the light emitting module 13 includes a first circuit board 130 with aplurality of light emitting components 131. The sensor and driver module15 at least includes a second circuit board 150 disposed with a sensordevice 151. These light emitting components 131 are LED light emittingcomponents. With such design, the light emitting components 131 arecapable of detecting whether human movement is existed by the sensordevice 151 and performs corresponding response of turn-on or turn-off.

FIG. 3 is an assembly portion of the first embodiment of the inductiveillumination apparatus of the present invention. Please also refer toFIGS. 2 and 3. The first circuit board 130 has an opening 130 a for thesecond circuit board to be disposed through the opening. Besides, thefirst circuit board may be an annual circuit board and the annualcircuit board defines an opening 130 as an annual hole. Alternatively,the first circuit board 130 may be an U shape circuit board (not shown),and the U shape circuit board defines an opening 130 a as an openopening. It is to be noted that the opening 130 a defined by the firstcircuit board 130 may have various shapes and the present invention isnot limited to illustrated shapes.

With such design, the spatial problem among multiple circuit boards issolved and thus the size of the circuit boards is not limitedaccordingly. As such, utilization of space is increased dramatically sothat components may have more flexible arrangement.

As mentioned above, because the spatial structure limitation of thecircuit board is unblocked, the sensor device is not necessary to bedisposed at peripheral portion of the inductive illumination apparatus 1as in conventional art. The sensor device 151 may be disposed near thecenter of the inductive illumination apparatus 1 to ensure the detectionrange of the sensor device 151 heads to same direction as theillumination range of the light emitting components 131.

If there is no spatial block problem among circuit boards, the structureof the first circuit board 130 may be a solid plate (not shown). Thesecond circuit board 150 disposed with the sensor device may beassembled to the first circuit board 130 via an electrical interface(not shown) and form a two-layers stack structure circuit module (notshown). Preferably, the second circuit board 150 may be disposed nearthe center of the first circuit board 130. Such design, however, is anexample but not a limitation to the present invention.

Moreover, because the light emitting components 131 are disposed aroundthe sensor device 151 to provide a surrounding 360 degrees illumination,the sensor device 151 does not shield the light emitting components 131in certain direction and does not decrease illumination efficiency ofthe inductive illumination apparatus 1.

Besides, the first circuit board 130 may be made such that the height ofthe first circuit board 130 near the center is larger than the heightthereof near the edge portion. Such design is increasing theillumination angle of the light emitting components 131, so as toincrease illumination brightness. This is also an option to implementthe present invention. Please refer FIG. 6 and following description.

Please refer to FIG. 2 again, because the opening 130 a of the firstcircuit board 130 is more close to the center portion and the firstcircuit board 130 is stacked upon the lamp body 11 so that the opening130 a is connected to a accommodation space 110 of the lamp body 11.With such design, a portion of the second circuit board 150 isaccommodated in the accommodation space 110 of the lamp body 11. Anotherportion of the second circuit board 150 is disposed through the opening130 a of the first circuit board 130 of the light emitting module 13.

In the following description, two different sensor devices are explainedas embodiments. In the embodiment using the first sensor device, thesensor device 151 of the sensor and driver module 15 is a passiveinfrared sensor component. In the embodiment using the second sensordevice, the sensor device 154 of the sensor and driver module 15 is amicrowave sensor component. Please refer to FIG. 8 and followingdescription.

In the first embodiment, the lamp body 11 further includes a lamp cup111, a center sleeve 112 and a lamp cap module 114. The accommodationspace 110 is defined by an inner edge surface by the lamp cup 111. Thecenter sleeve 112 is disposed through the internal side of the lamp cup.The second circuit is then disposed in the inner side of the centersleeve 112. The center sleeve 112 has two opposite ends. One end of thecenter sleeve 112 is connected to the lamp cap module 114. The other endof the center sleeve 112 is connected to bottom of the first circuitboard 130.

The sensor and driver module 15 further includes a glare shield 152disposed in the other side of the first circuit board with respect tothe center sleeve 112. The glare shield 152 shields the passive infraredsensor component to separate the passive infrared sensor component formthe light emitting component 131 to prevent the passive infrared sensorcomponent interfered by light or heat. Please also be noted that personsof ordinary skilled in the art may modify above design to clip the glareshield 152 and the center sleeve 112. Thus, the connection positionbetween the glare shield 152 and the center sleeve 112 is not limited tocertain configuration.

Specifically, the sensor and driver module may further include a lens153. The lens 153 is disposed at the end of the glare shield away formthe first circuit board so that when the lends 153 is connected to theglare shield 152, the lens 153 has a predetermined distance from thepassive infrared sensor component 151 in the glare shield 152. Thedistance between the lens 153 and the passive infrared sensor component151 is a factor to determine detection accuracy of the passive infraredsensor component 151. Therefore, positioning via structures may keep thelens 153 and the infrared sensor component 151 in an optimum distance.Therefore, with the design of the present invention, the passiveinfrared sensor component 151 may be kept at optimum position and heightand are not affected by human assembling, causing uncertain variation.

Besides, the inductive illumination apparatus 1 includes a transparentshade 17. The transparent lamp shade 17 shields the light emittingmodule 13 and is coupled to the lamp body 11. In response to the glareshield 152, the transparent lamp shade 17 has an opening hole 17 a attop. In addition, one of the glare shield 152 and the lens 153 isdisposed through or aligning with the opening hole 17 a to obtain betterdetection view.

The second circuit board 150 includes a sensorcircuit board 150 a and a driver circuit board 150 b. The sensor circuitboard 150 a is assembled to the assembling portion 150 f of the drivercircuit board 150 b and is electrically connected to the driver circuitboard 150 b. Preferably, the sensor circuit board 150 a and the drivercircuit board 150 b are perpendicularly disposed so that the detectiondirection of the sensor device 1501 disposed on the sensor circuit board150 a is parallel to the containing direction of the driver circuitboard to facilitate being stored and positioned.

In addition, the driver circuit board 150 b includes two electrodes 150c, a driver integrated circuit chip 150 d and a transformer 150 e. Inaddition, the lamp body 11 further includes a heat dissipation block 155a. The heat dissipation block 155 a may directly contact one of thedriver integrated circuit chip 150 d or the transformer 150 e.Alternatively, the heat dissipation block 155 a may indirectly contactat least one of the driver integrated circuit chip 150 d or thetransformer 150 e. By the flexible characteristic and good thermalconductivity of the silicon gasket 155 b, the silicon gasket 155 b isattached to at least one of the driver integrated circuit chip 150 d andthe transformer 150 e to facilitate heat dissipation.

In this embodiment, the lamp cap module 114 includes a lamp cap innertube 114 a, a conductive outer casing 114 b and a conductive component114 c. The conductive outer casing 114 b is sleeved on an outer surfaceof the lamp cap inner tube 114 a, and the conductive component 114 c isplugged in the bottom surface of the lamp cap inner tube 114 a. The lampcap inner tube 114 a is made of insulation material. After theconductive casing 114 b and the conductive component 114 c arerespectively connected to the lamp cap inner tube 114 a, the conductiveouter casing 114 b and the conductive component 114 c may serve as twoelectrode connecting points to a power source.

Moreover, the lamp body 11 further includes a first conductive pin 117and a second conductive pin 118. The first ends of the first conductivepin 117 and the second conductive pin 118 are respectively connected tothe two electrodes 150 c of the driver circuit board 150 b.

Next, the following description explains the second ends of the firstconductive pin 117 and the second conductive pin 118. The conductiveouter casing 114 b is sleeved to the lamp cap inner tube 114 a. That is,the conductive outer casing 114 b serves as an electrical connectingpoint. When the second end of the first conductive pin 117 is insertedto the crevice between the conductive outer casing 114 b and the lampcap inner tube 114, the second end of the first conductive pin 117 iselectrically connected to the conductive outer casing 114 b.

In addition, the conductive component 114 c is disposed through aconnection hole 114 d defined by the bottom of the lamp cap inner tube114 a, so that at least a portion of the conductive component 114 c isexposed outside the lamp cap inner tube 114 a to serve as anotherelectrical connecting point. Therefore, the second end of the secondconductive pin 118 is plugged into the connection hole 114 d to beelectrically connected to the conductive component 114 c.

With the above configuration, the first conductive pin 117 and thesecond conductive pin 118 are propped respectively to the conductiveouter casing 114 b and the conductive component 114 c to performelectrical connection. It is easier to be assembled without weldingtools. The efficiency of production is achieved and even further costdown.

The height near the centerportion of the first circuit board 230 of the light emitting module 23is larger than the height near the edge portion of the first circuitboard 230 of the light emitting module 23. Preferably, the first circuitboard 230 takes an angle of 5 degrees tilt to rise from the edge portionto the center portion so that a plurality of light emitting components231 disposed on the first circuit board 230 have larger jointillumination angle to obtain optimum illumination range and brightness.
